Note 510 — Chapter XI
Reading edition
Judging from the records of the chronicles of the period, it seems that William the Conqueror had not at any time a fleet capable of competing with those of the Northmen, who appear to have made descents on the coasts much as they had done in earlier years. Cf. Saxon Chronicle for the years 1069, 1070, 1083; and Selden, “Mare Clausum,” c. xxv.
